Removing Bathtub Stains for Under $20

I'm in the process of moving into an old historic home and boy, does it need work! The porcelain bathtub was disgusting, years worth of stains. For three days, I tried every "soap scum, mildew remover, etc." you could think of. Nothing worked (cue freak out) until I came across two lifesaving products.

1. Pumie Pumice Scouring Stick from Lowe's. $2.83 each. I used 4=$11.32. This is safe on porcelain, not enamel. Just wet the stick and scrub. It immediately started really removing stains. Once I ran out, I didn't feel like getting back in car so thought I would give the next product a try.
   

2. Bar Keepers Friend Cleanser, $2.50, local grocery store, Wal-Mart, Lowe's, etc. This stuff is amazing! I let it sit for a few minutes and scrubbed and it took everything nasty right off. I will never use another cleaning product! It's cheap and can also be used on so much more than just the bathroom.

So, including some scrub brushes from Dollar Tree, I spent around $16 and it looks like I bought a new tub! (The pink bottle in corner is just a cleaner I already had to wipe down tile.) I was so thrilled with outcome, I wanted to share with everyone! Hope this helps!

P.S. I forgot to take a legit "before pic". This before pic is right after I had started using the pumice stick. You can tell where it's been used on the right of pic.
